- Partnership to take the first step toward making plugging in obsolete -
Tokyo - September 27, 2011 - WiTricity Corporation (WiTricity), IHI Corporation (IHI) and Mitsubishi Motors Corporation (MMC) have agreed to join forces to research and develop easily deployable electric vehicle (EV) wireless charging systems readily compatible with electric grids which will make life easier for EV users in the future. The partnership structure of three major players in the wireless charging, electric infrastructure, and EV areas coming together will accelerate the popularization of wireless charging systems for EVs by developing systems that are usable "right out of the box" for individuals, governments, and other entities including power companies in order to make it easier and quicker for them to roll out such systems.

The aim of the collaboration is to make EVs remarkably more convenient for owners by accelerating the popularization (and thus availability) of wireless charging at homes and shopping center parking lots, etc.
Wireless charging systems allow transfer of energy from a source placed on or under the ground, to a vehicle equipped with an energy capture device. Charging occurs automatically when the vehicle is parked, with no physical contact between the vehicle and the charging source. WiTricity has already developed and brought to market its patented magnetic resonance wireless charging system*1. The system that WiTricity has developed can transfer energy further and more efficiently in comparison to conventional systems such as electromagnetic induction and microwave transmission, pushing the possibilities of wireless charging by being able to deliver up to 3.3 kW of charging power over distance of 20cm (almost 8 inches) at an efficiency rate of more than 90%, in manner that is safe and very user friendly. Systems based on WiTricity technology offer smaller size and lighter weight as compared to conventional systems, and operate with no moving parts.
